K99 Sleep Headband Bluetooth Wireless Audio Mask

The K99 Sleep Headband Bluetooth Wireless Audio Mask is a versatile 2-in-1 accessory designed to enhance your rest, relaxation, and sleep routines. By combining a soft, comfortable eye mask with integrated wireless Bluetooth headphones, this device allows you to listen to your favorite music, audiobooks, calming soundscapes, or guided meditations without the discomfort of traditional earbuds or headphones pressing against your ears. Crafted with a lightweight and ergonomic fabric design, it gently contours to your face and head while effectively blocking out ambient light to create a dark, peaceful environment anywhere you go.

Advantages

This wireless sleep mask offers exceptional comfort for side sleepers and back sleepers alike, as the built-in flat speakers eliminate hard plastic components that typically cause pain during extended wear. The breathable fabric material ensures a pleasant tactile experience throughout the night without excessive heat buildup. Equipped with wireless Bluetooth technology, it pairs seamlessly with smartphones, tablets, and other compatible audio devices to provide tangle-free listening. Furthermore, the integrated design serves a dual purpose by functioning simultaneously as an effective blackout eye mask and a personal audio system, making it ideal for travel, relaxation at home, or daytime naps.

Suitable for

• Listening to relaxing music or ambient sounds while falling asleep
• Enjoying audiobooks or podcasts in bed without disturbing a partner
• Practicing guided meditation and deep relaxation exercises
• Blocking light and noise during long-haul flights, train journeys, or commutes
• Resting during daytime shifts or in bright environments

When it may not be suitable

This product may not meet the needs of users who require active noise cancellation for extremely loud environments, as the fabric design relies primarily on passive light-blocking and standard audio delivery. Additionally, individuals who prefer high-fidelity studio sound with deep bass response might find the slim, integrated flat speakers less powerful than dedicated over-ear or in-ear headphones.

Key specifications

• Integrated wireless Bluetooth audio connectivity
• Soft, lightweight, and breathable fabric construction
• Ergonomic eye mask design for light blocking
• Flat-profile built-in speakers for side-sleeping comfort
• Rechargeable internal battery via USB

Control your audio playback and volume levels directly from your connected smartphone or tablet. When the fabric mask requires cleaning, carefully remove the electronic components from their internal pockets according to the manufacturer instructions before washing.
